Our ALD product candidates consist of a specific population of a patient’s own stem cells, which are isolated using our proprietary technology and 
which we believe have the potential to promote the regeneration of multiple types of cells and tissues, including the growth of new blood vessels. Our initial focus is on developing product candidates to address cardiovascular disease. Our cardiovascular product candidates are ALD-301 for the treatment of critical limb ischemia, ALD-201 for the treatment of ischemic heart failure, and ALD-401 for the post-acute treatment of ischemic stroke
